I Need Help Finishing Some of My Mario Kart Remastered Courses.

I only Have 7 days left before I have to return my Chromebook. But I still have a lot of Courses to Finish.

I need lots of Help to Finish Some of My Courses. Some of them are 3DS Rock Rock Mountain, GCN Dry Dry Desert, GBA Boo Lake, Wii U Cloudtop Cruise, and Mushroom Mountains.

If You are able to Finish those I'll be Very Happy. I really want to finish those but I'm trying to Finish Several Courses before Summer Break.

Challenge accepted

This one wasnt that hard, because i didnt have to do much changing, if you wanna change small things or add decors, that is fine

Thanks! There are some things I am going to Change. Like Minor Edits or Personal Touches. Custom Decors, ETC. Overall. You did a Great Job!
